The ailerons used approximately 1/4" on my balsa/foam wing. It did have gap seal, but I imagine that it will improve with a true composite wing, thus needing maybe 3/16" aileron throw.

The flaps work great on this plane to slow it down. Actually, it really didn't need them, but I liked having it. However, the wing used to be about 11% thickness and I have increased it to a little over 12% for the molded wing. This ought to reduce needed flaps a little. I am actually using the flaps for camber changing in the turns more than for landing. I don't think that I can get the 70 deg I used last time with the camber, but I'll live with 30 or 40 deg.

My elevator skin hinge came out great this time and if the wing is the same, I think it will be ok. The bottom line is that I've seen skin hinges work very well for long periods. I definitely overdid my brother's wing and I'm hoping the servos will take it. This one should be much better.
